The JBX05371 1.5m Ruckus Compatible 40GBASE-CR4 QSFP+ Passive Direct Attach Copper Cable represents an excellent solution for organizations seeking cost-effective, high-speed interconnectivity within their data center environments. This passive DAC cable eliminates the need for active electronics, reducing power consumption while maintaining exceptional signal integrity and performance reliability. Technical Specifications: The cable features precision-engineered 30AWG twinax copper conductors wrapped in durable plastic jacketing, providing optimal electrical characteristics and physical protection. With dimensions of 12x12x2 inches and a 1.5-meter length, this cable accommodates typical rack-to-rack distances in standard data center layouts. The QSFP+ (Quad Small Form-factor Pluggable Plus) connectors support bidirectional 40GB Ethernet transmission, fully qualified to IEEE 802.3ba standards and SFF-8436 specifications. Compatibility and Integration: Designed specifically for Ruckus network switches and compatible equipment, the JBX05371 is a direct replacement for OEM part numbers E40G-QSFP-C-0151 and E40G-QSFP-QSFP-P-0151. The passive architecture makes it compatible with Ruckus switches featuring QSFP+ ports without requiring additional power or active components. Compliance and Certifications: This cable meets stringent international standards including RoHS (Restriction of Hazardous Substances) and EU Directive 2002/95/EC, with additional TUV and UL safety certifications. These credentials ensure environmental responsibility and workplace safety compliance. Operating Conditions: With an operational temperature range of 0 to 70°C (32 to 158°F), the JBX05371 performs reliably in standard air-conditioned data centers and network closets. The cable maintains performance integrity across typical enterprise environmental conditions. Value Proposition: Passive DAC cables offer significant cost advantages over active optical alternatives while delivering comparable performance for shorter distances. The 1.5m length is ideal for intra-rack connections, providing superior ROI compared to longer-distance solutions. Custom brand programming is available for organizations requiring proprietary labeling or white-label solutions. Support and Service: Backed by a comprehensive 90-day limited warranty and shipped from convenient US distribution centers (Danville, CA and Beaufort, SC), the JBX05371 arrives quickly with free standard shipping on orders exceeding $99. This product represents a reliable, certified solution for enterprise networking infrastructure requiring high-speed, low-latency connectivity.
